Steam enters a diffuser operating at steady state with a pressure of 1 bar, a temperature of 150oC, and a velocity of 185 m/s. Steam exits the diffuser as a saturated vapor, with negligible kinetic energy. Heat transfer occurs from the steam to its surroundings at a rate of 12 kJ/kg of steam flowing. Neglecting potential energy effects, determine the exit pressure, in kPa.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
